The MMStar source `question` column already includes the options inline (e.g., 'Options: A: ..., B: ..., C: ..., D: ...'), so the template appends only the answer-format trailer. lmms-eval's mmstar task uses a different trailer ('Answer with the option\\'s letter from the given choices directly') and is not the canonical reference for the current prompt." | |
